ERNST BERGER, OF RORSCHACH, SWITZERLAND, ASSIGNOR TO THE FIRM OF HENRI LEVY, OF RORSCHACH, SWITZERLAND.

APPARATUS FGR FILLING THE SHUTTLES 0F EMBROIDERING-MACHINES.

Patented -Dec. 25, 1906 To all whom it may concern:

Be it known that I, ERNST BERGER, a subject'of the King of Wiirtemberg, Germany,

residing at Rorschach, Switzerland, have inusedin embroidering-machines is or maybe very large, in some cases as many as six hundred (600) needles are required, and the filling of the shuttles by the means heretofore available is very laborious and requires much time.

M invention has for its object to avoid the sadvantages referred to, and comprises mechanism for forming a cop within a shuttle, a shuttle-carrier, mechanism for moving the carrier eriodically, and thereby moving the em ty s uttles successively in position to be filled, mechanism for threading each shuttle after being filled, and mechanism for cutting the thread fed to the shuttle after it has been threaded.

In the accompanying drawings, Figure 1 is a front elevation, partly in section, of a machine embodying my invention. Fig. 2 is a fragmentary plan View, also partly in section; and Fig. 3 is a left end elevation, partly in section, on line A A of Fig. 1. Figs. 4 to 9 are detail views drawn to an enlarged scale, Figs. 4 and 5 being sections taken, res ectively, on lines B B and C C of Fig. 1. ig.

6 is a rear elevation of part of the mechanism shown in Fig. 5. Fig. 7 is a section on line D D of Fig. 9. Fig. 8 is a section on line E E of Fig. 7, and Fig. 9 a section on line F F of Fig. 7. Figs. 10 to 20 are also enlarged details illustrative of the successive steps in the operation of filling a shuttle, threading the same, and cutting the thread, Figs. 10, 12, and 14 being longitudinal vertical sections, Figs. 11, 13, 15, and 16 cross-sections, Figs. 17, 18, and 19 plan views, and Fig. 20 a side elevation, each of Figs. 11 to 20, showing a shuttle and a part or parts of the mechanism for filling and threading the same or for cutting the thread.

In order that the mechanism referred to may perform its functions automatically, as

its side walls, a, longitu hereinafter described, the shuttles 2 have besides the usual cover havi thread-a erture 16 and tension-s ring 17 t e inspect on-slot 9 and the threa -exit a erture 15 in one of posite side wall for traversing the thread along the cop-winding spindle, an aperture 3 in its rear wall for the introduction and with drawal of said spindle and the stripping off of the formed cop by such withdrawal, while the shuttle-cover is partly cut away at 18 to form a gap, the tension-s ring 17 being suit al slot 4 in its 013-,

ably recessed. Such a s uttle is shown in Figs. 10 to 20 and fully described in Letters Patent of the United States granted to me April 17, 1906, No. 817,744.

Referring now to Figs. 1, 2, and 3, the operative devices are mounted on or carried by a suitable frame 20, which has bearings for the main drivin shaft 23, to which are secured a belt-pulley 23, an eccentric 23", a beveled friction drive-wheel 22, and a worm 23. The strap-rod 81 ofthe eccentric 23 is connected to a radial arm 81" on a rock-shaft 81 having its hearings in a bracket secured to the main frame 20, and to said shaft is secured the thread-guide 7, whereb the latter is vibrated in front of the shutt e-slot 4 to traverse the shuttle-thread along the copwinding spindle 5, hereinafter referred to as the cop-spindle. (See also Figs. 7 and 8.) The frame 20 also has bearings for four parallel shafts arranged one above the other, all of which have endwise motion in their said bearin s. lef t end the shuttle-carrier 1 in the form of a disk having a peripheral flange, Fig. 2, from which project tongues 1 at equal distances a art, and the under side of said flange 1 at t e rear end of each tongue has an an ular seat 1 for the beak of a shuttle 2, whi e on the under side of the forward end of the tongue is a shoulder for the rear Wall of said 'The tongues 1 aresuita ly cut away to expose the thread-aperture 16 in the shuttlecover and to admit the thread being carried under the tension-spring l7 and across the gap or recess in said spring and across the gap 18 in .the shuttle-cover inthe threading of the shuttle, as hereinafter described.

On shaft 48 is mounted a coiled spring The lower shaft .48 has secured to its in itsnormal or operative positionjshown in Fig. 1, with a shuttle inposition to be filled, means hereinafter referred to being provided to move the shaft 48 and shuttle-carrier to the left sufficiently to cause the shuttle to move off the cop-winding'spindle, andthereby strip the cop ofl of said spindle, means being also rovided to then rotate the shaft and shutt e-carrier sufliciently to bring an empty shuttle into position for filling. The two shafts above shaft 48 are sectional or twopart shafts, the sections 28 and 27 of which carry coiled springs, 32 31, respectively, the tendency of which is to move the shafts to the right to. couple them to their respective right end sections 26 and 24, both sections of each shaft being provided with clutch-coup ling faces 30 and 29, respectively, of usual construction. Sections 26 and 24 of the two shafts carry each a worm-wheel 26 and 25*, respectively, meshing with each other, wheel 25 gearing with worm 23 on main drivingshaft 23, from which the shafts 24 27 and 26 28 can be driven. Each of the shaft-sections 26 and 24 also has a shifting collar engaged by a shifting-rod 77, connected to one arm of a weighted lever 74. To this lever is secured a spring-latch 72, engaging a fixed keeper 76, the free end of said latch lying in the path of a tripper-arin 71 on ratchet-wheel 49, con nected to shaft 48 by groove and feather and held against longitudinal motion with the shaft by a lug 66'" at the foot of an arm 66, securedto the main frame and having a segmental cam at its upper end, hereinafter referred to. The tripping of lever 74 raises the shifting-rod 77 and shifts the shaft-sections 26 24 toward the right, and thereby moves the worm-wheel 25 out of gear with the Simultane-' ously therewith the rod 77 actuates a bellworm 23? on main shaft 23.

crank lever 79 to throw the cop-winding shaft 19 out of gear, as will be presently described.

The part 28 of shaft 26 28 carries a gearwheel 42 in gear with a crown-wheel 43, having bearing in an arm 44, secured to the main frame 20. To the periphery of said wheel 43 is secured a pawl 45, adapted to engage the teeth of the ratchet-wheel 49 on shaft 48 at each revolution of the wheel 43 to rotate shaft 48 and impart to the shuttlecarrier 1 an angular movement equal to the distance between two shuttles. To the under side of the crown-wheel 43 diametrically opposite pawl 45, at 46, is pivoted a push-rod 47, extending to the left and in contact with the shuttle-carrier, 1, said rod being guided in the machine-frame, so that at each revolution of the crown-wheel the shuttle-carrier is moved to its leftextreme positionv and then rotated a step to bring an cam-face has two steps 68 and 67, which not only act on the projection 69 on hub of gearwheel 42, butalso on a nose 70 of a cam 41 on section 27 of shaft 24 27, which cam 41 has two other cam-noses 70 and 41 (See also Figs. 4 to 6.)- On said Section 27 of shaft 24 27 are secured two lifting-cams 33 and 34, the latter having a pin 59, adapted to engage a radial arm 58 on the right-hand end of a spindle 57, tothe left-hand end of which is secured the shuttle-threading hook 13, held in a retracted position by a spring 13, Fig.8; but when the pin 59 engages the arm 58 the spindle is turned to move the threading-hook 13 to the left, Fig. 8, through the thread-exit aperture 15 in the shuttle 2 to seize the shuttle-thread, Fig. 16, and draw it through said aperture. When pin 59 on cam 33 releases radial arm 58 on the threading-hook spindle, the latter is turned in an The hub opposite direction by spring 13, connected with said hook, Fig. 8,. to draw the shuttlethread out through shuttle-aperturelii.

At its left end the section 27 of shaft 24 27 has a collar 61, which is partly cylindrical and partly conical or tapering inwardly, and 8 is a feeler-lever fulcrumed on a stud on the main frame, its upper bent arm adapted to project through the inspection-slot 9 of the shuttle 2 in contact with the cop-winding spindle, Fig. 11. The lower arm 60 of said lever 8 during the formation of a cop lies in contact with the inner face of the aforesaid collar 61, and its function will be presently described.

At its right end thecop-winding shaft 19 carries a conical friction'drive-wheel having sliding motion on said shaft but rotating therewith, said cone-wheel being driven by the friction bevel-wheel 22 on main shaft 23. A coiled spring on shaft 19, acting on the hub ofcone-Wheel 65, tends to maintain the same in frictional contact with drive-wheel 22, and on said hub of cone-wheel 21 is mounteda sliding collar connected by a rod 64 to a lever 63, fulcrumed to the main frame,

when the latter is rocked by the shifting-rod 77 on the release of weighted lever 74, above described, the bell-crank lever will act on the lug 80 and push the rod '64 toward the left, thereby moving driven cone-wheel 21 out of contac with driving wheel 22. On the cop-winding spindle 5, which is also tubular and has an annular peripheral groove 14, Figs. '10, 12, and 14. The shaft19 in rear of i the cop-spindle is slotted longitudinally, as

' rocking bearing for the hub of a lever 37,

shown at 19, Fig. 7, to form a guide for a pin 19, secured to a sliding collar 19, connected to the upper arm of a lever 55, actuated by the lever 53, above referred to. The pin 19 passes through a slide-block 19, to which is secured a rod or wire 6, having a hook at its left end. A spring 85, coiled about said rod and abutting against the winding-spindle 5 and slide-block 19 tends to move the rod 6 toward the right. When the push-bar 47 moves toward the left, its lug 52 turns lever 55 toward the right to project the hook-rod 6 from the spindle 5, for purposes presently explained.

I will now describe the shuttle-threading devices: Above the main frame is located a pin or spindle 37 securedto and carried by the vertical arm of an angle-lever 39, fulcrumed on the machine-frame, and said spindle has an enlargement 37", Fig. 2, to form a constructed in the form of an oblong rectangularframe, in the cross-bar, at the free end of which is secured a tubular rod 10, tapered at its lower end. The front longitudinal bar of the lever 37 has a lateral extension to which is secured a depending foot 35, which rests on the lifting-cam 33, Fig. 1. On the hubof lever 37 is mounted a second lever 38, having a longitudinal slot 38 at its outer end for a transverse pin 38, to which is pivoted a rod 11, which has vertical motion in the tubular rod 10 and has a hook 12 at its lower end. (See also Figs. 7, 8, and 10 and Figs. 12 to 16.) To the free end of lever 38 is also secured a vertical guide-pin 82, projecting through a longitudinal slot 83 in an overhanging bracket 83 on top of the machine.- frame 20, said slot being formed of two parallel portions out of line with each other, Fig. 2, and said lever has a lateral extension 36 extending over the front longitudinal bar of frame-lever 37," to which extension is secured a depending foot 36, which rests on cam 34 on shaft 19. By means of the described arrangement suflicient lateral move-- ment is afforded to the levers 36 and 37 to permit the guide-pin 81 to move from the left end of the slot 83 into and along its righthand end. The lever 39 is connected to the machine-frame bya spring 39, and the horizontal arm 40 of said lever bears on cam 41 on section 27 of shaft 24 27 and is periodically tiltedby the cam-nose 41 of said cam to move the levers 37 and 38 from left to right,

the reverse movement being effected by the spring 39 when cam-nose 41 ceases to act on lever-arm 40, as will be readily understood.

The devices for cutting the feed-thread comprise a yoke 54, pivoted to the machine frame and having a downwardly-projecting arm 54, between which and the lower arm of the lever 55 lies the up er arm of the vertical lever 53, actuated by t e lug 52 on the push bar 47, above referred to. It will be seen that when the push-bar 47 moves the shuttle-carrier to the left and actuates lever 53, and thereby lever 55 to project the hooked rod 6 in the cop-winding'spindle 5 out of the latter, the lever 54 will not be afiected; but after said lug moves out of contact with the lever 53 and makes its return movement said lever 52 will actuate lever 54, and thereby raise the yoke 54. The cross-bar 54 of the yoke carries two shear-blades. One, 56, is pivotally connected to the fixed blade, Fig; 8. The movable blade 56 is held open by a spring 56 and has an extension 56 in the path of a pin 88, so that when yoke 54 is lifted the pin 88, acting on arm 56, closes the movable blade 56 against the tension of its spring 56", and when said yoke again drops said spring opens the movable blade, as will be readily seen.

It being assumed that thread is fed to a shuttle from any conveniently located threadfeed and that the end of said thread has been threaded through the eye of the threadguide 7 and by the projection of the hooked rod in the cop-winding spindle seized, drawn into said spindle, and held therein, the operation of the machine will be as follows, the parts being shown in Figs. '1 to 6 and 10 and 11 in their respective positions for beginning the winding of a cop-that is to say, a shuttle 2 has been moved onto the cop-winding spindle 5 by the movement of the-carrier 1 IIO from left to right, the driven friction-cone 21 on the winding-shaft 19 is in contact with the driving-cone 22 on the main shaft 23, threading hook 13 withdrawn, the upper feeler-arm of the feeler 8 in contact with the winding spindle 5, position I, Fig. 11, the lower arm 60 of said feeler on the right of the collar or head 61 at the left end of section 27 of shaft 24 27, whereby said shaft-section 27 has been moved sufficiently toward the left to uncouple it from its section 24 and com press the spring 31 on said section 27, while shaft-section 28 is also uncoupled from its section 26 and the spring on said section28 compressed. The main shaft 23 bei now rotated a cop is wound on the spind e, and as said cop increases in-diameter the upper arm of the feeler 8 is forced outwardly against the stress of its spring 62, connected ,to its arm 60, Fig. 8, while said arm 60 is moved away by arrow,

from .head 61 on shaft-section 27 until the cop is com leted, when arm 60 of the feelerlever 8 Wil have moved along the inclined face of head 61 to the cylindrical portion of said head,.thereby moving the feeler 8 out of the shuttle 2 and releasing shaft 27, which is now coupled to its section 24 by the action of the spring 31, and said shaft is rotated by the gearin 23 25 in the direction indicated ig. 1. By this movementof the shaft-section 27 the hub of cam 34 acts on lever 63 and through its connecting-rod 64 moves the driven cone 21 toward the left against the stress of spring 65 and out of contact with drive-wheel 2 2,thereby stoppi the rotation of winding-shaft 19. As sha- 24 27 now rotates the noses of the two .cams 33 34 move from under the feet 35 36of the levers 37 and 38, causing them to drop, thereby bringing the tapering end of the tube 10 over and in register with the thread-aperture 16 in the shuttle-cover, with the rod 11 projecting into the shuttle-and with its hook 12 in the annular groove 14 at withdraw the rod 11 into the tubu'ar rod after having hooked the co -thread stretched across the annular spin le-groove 14, position III, Figs. 14 and 15-. Atabout the same time the pin 59, projecting from cars 33, engages the radial arm 58 on the threading-hook s indle and turns said shaft to move the hoo through the thread-aperture 15 into the shuttle 2, 16,. and about this time the cam-nose 41 on cam 41 on shaft-section 27 tilts lever 39 toward the right, thereby moving levers ,37 38 in the same direction, and under the guidanceof the pin 82 in slot 83 in frame-bracket 83 the tubular rod 10 will be movedfroni the position III above the thread-aperture 16 in the shuttle-cover to the position IV, 17. By this movement the thread end held in the windi -spindle, and now also held in the tubular ro 10,. is drawn out of said spindle, then under the tension-spring 17 and across the gap 18 in the shuttle-rover and across the hook of the threadinghook 13, at which time the pin 59 on cam 34 releases arm 58 on thethreading-hook. spindle 57, and under the action of the spring 13 of hook 13, the latterandwith it the endof the cop-thread is drawn or threaded through the eye or ap erture 15 in the side wall of the shuttle 2, positionV, 18. After the threading of the shuttle the cam-nose 41 on cam 41 moves out of contact with arm 40 of lever 39, causing levers 37 38 to betilted back toward the left, at which time cams 33 and 34 lift said levers to their position of rest.

Shortly before the completion of the operations last described the cam-nose 70 on cam 41 moves onto the first step 67 of the fixed cam 66, and cam-nose 7 O of cam 41 at the same time acts on'projection 69 on the hub of gear-wheel 42 on section 28 of shaft 26-28 which is then on the second step 68 of said fixed cam, to hold the uncoupled shaft-section 28 against the stress of its spring 32. The action of cam-nose 7 0 on projection 69 is such as to move the latter off'st'ep 68 on fixed cam 66, and thereby release shaft-section 28 and cause-its spring 32 to couple it to its'section 26, whereby said shaft is rotated by gearing 23 25 26*. At the same time the cam-nose 70 of cam 41 moves onto the step 67 of fixed cam 66, thereby camming shaft-section 27 toward the left and uncoupling the same from its section 24 and thereby bringing arm of feeler 8 again in frontof collar 61, Fig. 1. .The rotation of shaft 26-28 also rotates crown-wheel 43 through gear 42, the former moving the push rod 47, and through the latter the shuttlecarrier 1 toward-the left,.whereby the threaded copisstripped off the winding-spindle 5. During this movement of the push-rod 47 lug 52 thereon acts on lever 55, thereby projecting the hook-rod 6 from .the windingspindle 5 in position to hook the thread leading from the thread-guide 7 to the cop, which thread is drawn out of the shuttle by the hook-rod 6 as the shuttle-carrier 1 moves to the of its position toward the left. (Position VI of shuttle and winding-spindle, Fig. 19.) At this time the pawl 45 on the crown-wheel 43 engages a tooth of ratchetwheel 49 and rotates the same, thereby imparting to the shuttle-carrier 1 an angular movement suflicient to bring an empty shut tle in line with the winding-spindle 5. The previously-filled shuttle will now occupyposition VII, Fig. 19, relatively to the windingspindle, with the feed-thread held by the hook-rod 6 in said spindle. During the movement of the push-rod 47 toward the left its lug 52 will move out of contact with lever 53, causing the spring 85 to retract the hook-rod 6 into the spindle to hold the feedthread ready for the winding of the next cop. On the return movement of the push-rod 47 the lug 52 thereon acts on lever-arm 54, lifts the shear-frame 54 with the 0 en blades of the shears straddling the three from the cop in the filled shuttle to the hook-rod 6 in spindle 5, when the movable shear-blade is closed by the means before described and said thread is cut, leaving the feed-thread from the thread-guide 7 to the hook-rod jammed in spindle 5 ready for the winding of a cop, and as lug 52 moves. out of contact with lever 53 the shear-frame drops to its normal posi- IIO tion. This movement of the shuttle-carrier from left to right under the stress of the spring 51 on the carrier-shaft 48 moves the empty shuttle, previously positioned, onto the winding-spindle 5. At the same time the projection 69 on hub of toothed wheel 42 moves onto the first step 68 of fixed cam 66.

and moves the nose 70 of cam 41 onto the second step 69 of said fixed cam, thereby camming shaft-section 28 toward the left and uncoupling the same from its section 26. Shaft-section 27 is uncoupled from its section, as above described, at the same time shaftsection 28 is uncoupled from 26, and as cam 34 moves to the left with shaft-section 27, which movement is followed by the lever 63 under the stress of spring 65 on cop-winding shaft 19, the latter is moved in an opposite direction by said spring, moving driven friction-cone 21 thereon in contact with driving-cone 22, all the mechanism bein again in the position Fig. 1, and the described operations will be repeated until all the shuttles on the carrier have been filled.

In the drawings I have shown as an example a shuttle-carrier adapted to carry twentyfour shuttles. When the last shuttle has been filled, the tripping-arm on ratchetwheel 49 engages the spring-catch 72 and releases lever 74, whereby shafts 19 and shaftsections 24 and 26 are shifted to throw the driven gearing out of gear with the drivinggearing by the mechanism hereinbefore describe I claim 1.
